Delta Ohm HD37AB1347 Datalogger for IAQ Analysis

The HD37AB1347 IAQ Monitor is an instrument for the analysis of indoor air quality (IAQ, Indoor Air Quality). The instrument simultaneously measures the following parameters, using the P37AB147 SICRAM probe: CO2 Carbon Dioxide, CO Carbon Monoxide, Temperature, Relative Humidity, it calculates Dew Point, Wet Bulb Temperature, Absolute Humidity, Mixing Ratio, Enthalpy and Atmospheric Pressure. You can also connect Temperature and Humidity SICRAM combined probes, Hot-Wire Sensor Wind Speed SICRAM probes, Vane Wind Speed SICRAM probes, and Temperature SICRAM probes with Pt100 sensor, to the instrument.

The instrument, using a proper procedure, calculates the percentage of external air input (% Outside Air) according to CO2 Carbon Dioxide, temperature, and Ventilation Rate.

The HD37AB1347 is a datalogger with a memory capacity of 67600 recordings per each of the two inputs, divided in 64 blocks. It uses the DeltaLog10 software downloadable from the Delta OHM website. Reference Standards: ASHRAE 62.1, Legislative Decree 81/2008. These regulations apply to all confined spaces that could be used by people. Kitchens, baths, changing rooms and swimming pools are included, due to their high humidity. You should take into account, in regard to air quality, possible chemical, physical and biological contaminants, or the input of non-sufficiently purified external air (Ventilation Rate).

The instrument has a wide Dot Matrix graphic display with a resolution of 160x160 dots.

The instrument typical applications, using the above range of probes, are:

• Measurement of IAQ (Indoor Air Quality) and comfort conditions in schools, offices and indoor spaces.
• Analysis and study of the Sick Building Syndrome, and of the resulting consequences.
• Checking the HVAC (Heating, Ventilation and Air Conditioning) system efficiency.
• Examination of IAQ conditions in factories to optimize microclimate and improve productivity.
• Building Automation checks.
